1 Claim.

This invention appertains to new and useful improvements in washers of the type especially adapted for washing ore, stone, sand, etc.

The principal object of the present invention is to provide a washer wherein a rotary drum is provided of polygonal cross-section to the end that the substance being washed will be thrown from one plane to another and not continuously whirled around on a cylindrical wall as is now done in cylindrical type washers.

Another important object of the invention is to provide a washer constructed in such a manner as to cause cutting and disintegration of the material being washed.

These and various other important objects of the invention will become apparent to the reader of the following specification.

In the drawings:-

Figure 1 represents a side elevational view of the machine with a portion broken away.

Figure 2 represents an end elevational View of the washer.

Figure 3 is a cross-sectional view on the line 3-3 of Figure 1.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the drum 5 is shown of square cross-section, but obviously the same can be of any desired polygonal cross-section, so long as the side wall is in the form of merging planes in contrast to the smooth type of cylindrical drums now found in conventional washers.

The drum 5 is of longitudinally tapering construction and has an internal shell 6 or lining of thin metal from which a multiplicity of fins 1 are struck and caused to project inwardly, and these fins are in rows following spirals extending from the large end A of the machine to the small outlet end B.

Number 8 is a base upon which the bearing assemblies 99, Ill-40 and l l-l I are mounted. The two end bearing assemblies, 9-9 and llH carry the weight of the machine; the end figures 1937, Serial No. 137,124

|2l2 are not gears, but are friction rings and rollers, while the centre figure carries all the gearing including the ring gear I4 and pinion l 2. One of the shafts of the bearing assembly lEL-l i] has a gear wheel it carried thereby, and this meshes with a pinion ll on a countershaft 68 along with the sprocket wheel I9. On the base 8 is electric motor 20, the armature shaft of which has a small sprocket wheel 2!, and over this sprocket wheel 2 l, and the sprocket i9, is trained the sprocket chain 22. Thus the drum 5 is rotated by motor 20. Numeral 23 represents a suitably supported hopper having chute 24 depending into the inlet end of the drum 5.

Obviously, with the plane sides of the drum 5 and the square-shaped fins l projecting into the drum from the shell 6, the substance which is placed in the drum for washing is caused to feed from the inlet end to the reduced outlet end B and in this transit will be thoroughly broken and disintegrated.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size, and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the claimed as new is:-

The herein described specific improvement in an ore Washer, comprising essentially a horizontally mounted drum tapered in the direction of its length and rotatable about its axis, and a shell or lining of thin metal arranged close against the inner side of the drum and having struck therefrom a multiplicity of fins extending inwardly from the major portion of the shell or lining and arranged in spaced rows forming spirals extending from the inlet end of the drum to the outlet end thereof, the drum and shell or lining being of polygonal cross-section.

invention, what is WILLIAM A. FYE.
